Company Description

Profitable, independent legaltech company turning unstructured contracts into verified data for AI applications

Job Description

Join a high-trust engineering team of four building the verified foundation for legal AI. You will own problems end-to-end—from user research and design to infrastructure and deployment. Using a "deliberately boring" tech stack of Python, Django, and TypeScript, you'll solve complex data extraction challenges where precision is paramount and edge cases are endless.

Location

London, UK

Why this role is remarkable

• Work in a high-autonomy environment where engineers are treated as product owners, making critical design decisions rather than just executing tickets.
• Join a profitable, self-sustaining company that prioritizes quality and craft over VC-driven growth cycles, ensuring long-term stability and deliberate shipping.
• Tackle technically deep problems involving messy legal data and high-stakes verification where your work directly prevents AI hallucinations in the legal sector.

What You Will Do

• Own entire features across the full stack, including backend logic in Django, frontend interactions with HTMX, and cloud infrastructure management.
• Conduct direct user research to understand legal workflows and translate those insights into clean, compositional code and robust system abstractions.
• Collaborate with a multidisciplinary team of physics, cognitive science, and fintech experts to maintain a high-quality codebase focused on type safety and testing.

The ideal candidate

• Demonstrates strong functional programming aptitude and rigorous, compositional thinking to produce maintainable, clean code regardless of specific language history.
• Has a proven track record of shipping production-grade features end-to-end and taking full ownership of the product lifecycle in a professional setting.
• Thrives in a small-team environment with high independence, identifying and fixing architectural or product problems without needing external direction.

Who are Jack & Jill?

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.

How does this work?

• Jack's an AI agent for job searching and career coaching. He works for you.
• Jill is the AI recruiter working for the company. She recruits from Jack's network.
• If it's a match and the company wants to meet you, they'll make the intro. In the meantime, if you'd like, Jack will send you excellent alternatives.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
